The air defense system of great Britain. (part 2)

In the mid-50s, it became clear that the british fighters are far behind the american and soviet peers. While in other countries commercially built and was adopted not only interceptors, but also a supersonic front-line fighter in the royal air force continued operation and production of the subsonic machines. Moreover, the combat debut of the british gloster meteor in the fighting in Korea demonstrated their complete failure in the role of front-line fighter. However, the probability maneuverable air combat with soviet fighters over the british isles was low, and the raf was not similar to the american f-100 ", supercar" or the soviet mig-19, while supersonic all-weather interceptor with high overclocking performance, is equipped with a powerful radar, guns and guided missiles.

The creation of such machines was in the company of english electric ( in 1960 became part of british aircraft corporation) with the end of the 40-ies. On the plane, received the name of lightning (lightning) was sold to many original technical solutions. According to the adopted in those years the concept of creating an interceptor, radar, armament and controls were linked so to provide all-weather intercept within range of the onboard radar and automatically track and destroy it without the mandatory participation of the pilot. On "Lightning" cockpit to provide a better view was raised over the fuselage.

As a result of increasing the level of the cabin has increased the size of the fairing that allowed it to knead the fuel tank and elements of avionics. The fighter could carry two missiles air combat firestreak infrared homing head and a pair of 30-mm guns "Aden", installed in the upper forward fuselage. Guided missiles could be replaced with two blocks with 36 68-mm nar, or even two 30-mm cannons. The plane had a wing with a sweep of 60 ° and two stacked turbojet engine rolls royce avon 210p, traction 6545 kgs each.

Another innovation was the adjustable air intake with a generator of shock waves in the form of a central movable cone, inside of which was placed a monopulse radar ferranti ai. 23 able to detect the bomber at the distance of 64 km from the radar was interfaced computerized fire control system that in automatic mode with the involvement of the autopilot in the ideal was to withdraw the interceptor at an optimal position for the launch and capture target homing, after which the pilot had only to press the start button missiles. F. 1эксплуатация lightning interceptor lightning f. 1 in front-line squadrons began in 1960.

Planes the first models were suffering from numerous "Children's ills" and had insufficient range. Due to the crude construction and lack of spare parts readiness "Lightning" was initially low. Almost immediately after the start of series production in construction began to make improvements. The aircraft was refueling in the air and a more powerful engine.

The first public demonstration of a new interceptor took place at the air show in farnborough in 1961. At the end of 1962 came into operation interceptors modifications f. 2. In this version, changes were made in order to improve the stability and controllability of the aircraft. The f.

2a variant to increase range of flight was not reset external 2800 litre tank. Because of this, combat radius of action of the interceptor has increased significantly, and the lightning f. 2a is placed on british bases in Germany to perform low-altitude interception of soviet il-28. Lightning f.

3 landing at the airbase penbrokeshire the series went to lightning f. 3, with a new avon 301r engines and tail larger. Improved aerodynamics and more powerful engines increased the maximum speed to 2450 km / h upgraded radar ai. 23b and ur red tor allowed to carry out the attack goal "In a forehead", but the interceptor stripped of built-in guns. On the model f.

3a capacity internal fuel tanks brought to 3260 liters, it is also possible suspension drop tank with a capacity of 2800 litres. The last production version was the lightning f. 6. In general, it was identical to the f.

3, with the exception of the ability of the suspension discharged two 1200 liter ptb. Later in connection with raf claims about the lack of on board built-in interceptor weapons on the modification of f. 6a in the forward fuselage returned two "Adanowsky" thirty. The addition of the cannons and their ammunition decreased the amount of fuel on board to 2770 2430 liters, but the guns expanded the capabilities of the interceptor, which, after a volley of two missiles was unarmed.

Yes, and the missiles firestreak and red top with thermal homing heads was far from perfect, had a low noise immunity and a small launch range. Interceptor lightning f. 6a c weight 20,752 kg, had a range 1370 km ( with external tanks up to 2040 km). Supersonic intercept radius was 250 km.

The weak point of all the "Lightning" was a small radius of action. However, over time the interceptor had unparalleled overclocking performance and rate of climb. In terms of climb (15 km/min) it surpassed not only many of his contemporaries, but later fighters: mirage iiie – 10 km/min, the mig-21 – 12 km/min, and even тornado f. 3 – 13 km/min.

The pilots of american f-15s flying with the "Lightning" later modifications noted that the booster characteristics of the british fighter is not inferior to their much more modern machines. Despite the fact that "Lightning" has long withdrawn from service its elevation data has never officially disclosed. Representatives of the royal air force of great Britain during presentations at air shows, said that the maximum altitude exceeds 18,000 m. However, in fact, the interceptor can fly at a much higher altitude.

In 1984, during a joint U.S. -british exercise was carried out successful interception of high-altitude reconnaissance u-2. Only in the UK, given the prototype, export orders, and a training double machines have been built 337 "Lightning". Operation interceptors in the raf ended in 1988, after almost 30 years of service. In the second half of the ' 70s, "Lightning" in squadrons of interceptors seriously pressed american f-4 phantom ii.

Initially the british in 1969, purchased U.S. 116 f-4m (phantom fgr. The mk ii) and f-4k (phantom fg. 1) representing a "Britanizirovannye" version of the f-4j with engines rolls-royce "Spey" mk. 202 and avionics british production. English f-4m was received in fighter-bomber squadron stationed in Germany. But after adopting aircraft sepecat jaguar attack "Ghosts" are relocated on the british airfields.

Even more interesting collision happened with the naval f-4k. Soon after the purchase of carrier-based interceptors and the development of their pilots, the leadership of great Britain, in order to save budget, has decided to abandon the full-fledged aircraft carriers, and consequently deck "Phantoms" in the royal navy was "Irrelevant". In the end, all available raf f-4m and f-4k was converted into interceptors. Overall, the aircraft is good for this fit.

The benefits of "Phantom" before the "Lightning" was the long duration of the flight, powerful radar and medium-range missiles aim-7 sparrow semiactive radar homing. Missiles "Sparrow" from the mid-60s were equipped with rod warhead weighing 30 kg and proximity fuses. Compared to standard missiles the british "Lightning", sd aim-7 sparrow had a much better combat characteristics and could hit targets at a distance of 30 km flight together british interceptor "Lightning" and "Phantom"For a long time, "Lightning" and "Phantoms" in parallel, served in the air defense squadrons of the royal air force. As the decommissioning of the early models of the lightning f.

2 and f. 3 to compensate for the lack of technology in 1984, the royal air force has purchased 15 f-4j us navy. In addition to english airfields a few interceptors 1435-th level was located at the airbase mount pleasant in the falkland islands. The end of the cold war and the development in front-line squadrons of fighter-interceptor tornado adv was the reason for the decommissioning of "Phantoms".

The last 56 squadron, known as the "Firebirds" have handed over the f-4 in late 1992. Simultaneously with interceptor "Lightning" the british defense ministry initiated the creation of anti-aircraft missile complex long-range. To the finish line came two s look very similar to missiles: thunderbird (eng. "Petrel") – company english electric and bloodhound (eng. "The hound") – the company bristol.

Both missiles had a relatively narrow cylindrical body with a conical fairing and large tail feathers, but distinguished by type used in propulsion systems. On the side surfaces of the missiles were attached four discharged starting solid-fuel accelerator. Unlike anti-aircraft missiles of the first generation with radio command guidance system, established in the United States and the Soviet Union, the british from the beginning for his sam had planned to use semi-active homing head in combination with radar "Ferranti" type 83. To capture, support and guidance of anti-aircraft missiles at the target were used, the radar illumination is like a spotlight illuminated target for homing.

This guidance method was compared with the radio command greater accuracy and was not dependent on the skills of the operator guidance. In 1958 sam the thunderbird entered service in the 36th and 37th heavy anti-aircraft regiments, air defense of ground troops. Sam originally served for the protection of important industrial and military targets in the UK, but in the first half of the 60s all anti-aircraft missile regiments of the army were transferred to the rhine army. The length of the solid rocket modifications of the mk 1 was 6350 mm, and the diameter - 527 mm. For its time, solid-fuel missiles "Thunderbird" had a very high data.
